ABSTRACT:
A pair of upper crossheads for a universal rolling mill is engaged with nut assemblies on extended ends of a pair of screwdown spindles. Each crosshead can be swung about a nut assembly on one of the screwdown spindles while disengaged from a nut assembly on the other screwdown spindle for pivotal movement of the crosshead to one side of the housing frame. The nut assemblies for the ends of the crossheads, which remain engaged with the screwdown spindles, have threads that raise the crossheads during pivotal movement. Pedestal supports on projecting wing portions of the frame carry the pivoted parts of the crossheads. During operation of the universal rolling mill, the upper crossheads are held in their operative position by a clamp engaged with a crosstie that extends between two nut assemblies that can be exposed.
